This elegant loop relies on Mystic Sanctuary entering the battlefield untapped through Ghostly Flicker's ability to constantly recycle Ghostly Flicker back to the top of your library. Magus of the Future then lets you cast that exact instant straight off the top of your library, fueled by the green mana generated when you tap The Great Henge. Every iteration nets you life and sets up the next cast, and because The Great Henge is being constantly blinked, you can also leverage its static ability to draw through your entire deck alongside those repeated artifact entries.
